0–100, higher is better. How it is calculated

TopGis, s.r.o. is a Czech Republic-based company specializing in geographic information system (GIS) services and web-based map portals for municipalities, cities, and infrastructure operators. The company has positioned itself as a reliable successor to Bio-Nexus and Cleerio by acquiring their clients and technology, offering a modern GIS platform called GisOnline.cz. Their services include digital technical maps (DTM), cadastral data integration, 3D visualization, and smart city sensor data management. The website reflects a professional and government-focused business with clear contact information and compliance with basic privacy and cookie consent requirements. Technically, the website uses modern web technologies including JavaScript, Google Tag Manager, and cookie consent scripts. It is served over HTTPS with a moderate performance profile and good mobile optimization. However, the site lacks explicit privacy and terms of service pages, and no advanced security headers were detected, suggesting room for improvement in security posture. From a security perspective, the site enforces HTTPS and uses cookie consent mechanisms, but the absence of security policies, incident response contacts, and vulnerability disclosure information indicates a moderate security maturity level. The missing WHOIS data reduces domain trust signals, although the website content and company information appear legitimate and professional. Overall, the website is well-designed and informative, targeting public administration entities in the Czech Republic. Strategic recommendations include enhancing security headers, publishing privacy and security policies, and improving domain registration transparency to strengthen trust and compliance.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

TopGis operates in the government and technology sectors, providing GIS solutions primarily to municipalities and public administration in the Czech Republic. Their competitive advantage lies in proprietary data, a modern web GIS platform, and a strong client base inherited from Bio-Nexus/Cleerio. The business model is B2B SaaS and service-oriented, with revenue streams from software licensing, data hosting, consulting, and mapping services. The company targets municipal governments, infrastructure operators, and investors, emphasizing compliance with Czech legal requirements for digital technical maps. Growth indicators include acquisition of legacy clients and continuous platform development. Partnerships with former Bio-Nexus clients and integration of advanced mapping technologies position TopGis as a market leader in Czech GIS services.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is enforced, and cookie consent mechanisms are implemented, indicating awareness of privacy regulations. However, the absence of key security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces protection against common web attacks. No incident response or vulnerability disclosure information is provided, limiting transparency and readiness for security incidents. The lack of WHOIS data undermines domain trustworthiness. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security maturity is adequate for informational purposes but requires enhancements to meet higher compliance and security standards.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Publish clear and accessible privacy policy and terms of service pages to improve compliance and user trust.
  3. Provide incident response contact information and consider publishing a security.txt file for vulnerability disclosure.
  4. Investigate and resolve WHOIS data availability issues to improve domain transparency and trust.
  5. Regularly audit third-party scripts and tracking tools to ensure they do not introduce vulnerabilities or privacy risks.

Technical notes

Notes

The website uses a modern web technology stack including JavaScript, Google Tag Manager for analytics, and a cookie consent management script. The HTML and CSS are valid and support responsive design, providing good mobile optimization and user experience. Performance is moderate, with asynchronous loading of scripts to improve page load times. The site lacks a detected CMS, suggesting a custom or proprietary platform. Hosting provider details are not evident from the content. Accessibility features are basic but present. SEO optimization is good with proper meta tags and structured navigation. Opportunities exist to improve technical security configurations and add structured data for enhanced search visibility.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
